Just took my new P2 out of the box, upgraded to 3.06, did advanced calibration and controller calibration in the P2 assistant software. Did field compass calibration and flew the P2 a little in Phantom mode. It seems to fly well in GPS mode but one motor is noticeably stiffer when the rotor is spun by hand and visually slower when the P2 is just idling. That slow motor pulses every couple of seconds at idle very consistently too. Is this an issue? Lastly, when the P2 is turned on, the startup sounds are delayed between the two speakers that output them. My last P2 didnt have either of these issues. Thoughts?
